About the Decimal to Binary Converter

Decimal to Binary Converter converts numbers between bases. Programmers work with several number systems — binary (base 2), octal (base 8), decimal (base 10) and hexadecimal (base 16) — and this tool converts Decimal to Binary accurately, handling multiple space-separated values at once.

How Decimal to Binary works

Repeatedly divide by 2 and read the remainders from bottom to top.

Worked example: 13 = 8 + 4 + 1 = 1101
